指针是Ｃ语言中广泛使用的一种数据类型。 运用指针编程是Ｃ语言最主要的风格之一。利用指针变量可以表示各种数据结构； 能很方便地使用数组和字符串； 并能象汇编语言一样处理内存地址，从而编出精练而高效的程序。指针极大地丰富了Ｃ语言的功能。 学习指针是学习Ｃ语言中最重要的一环， 能否正确理解和使用指针是我们是否掌握Ｃ语言的一个标志。同时， 指针也是Ｃ语言中最为困难的一部分，在学习中除了要正确理解基本概念，还必须要多编程，上机调试。只要作到这些，指针也是不难掌握的。-target is C language widely used in a data type. Guidelines used C programming language is the most important one of the style. Use pointer variables can be expressed various data structure; Can be very convenient to use arrays and strings; and like assembly language can deal with the same memory address, which came up with a streamlined and efficient procedures. Guidelines have greatly enriched the C language function. Learning targets C language learning is the most important aspect of a the correct understanding and use of indicators is the availability of a C language signs. Meanwhile, the target is C language most difficult part of the study, in addition to correctly understand the basic concepts, There was also a need to more programming, debugging on the plane. If achieved these tar
